senr-ADJUSTING OUTLET-Box.

Specification of Letters Patent.

Patented Apr. 15, 1913.

Application mea January 4, 11912. serial No. 669,364.

To all whom t may concern Be it known that I, OMER F. Dominant., a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented new and useful Improvements in Self- Adjusting Outlet- Boxes,.of which the following is a specilication.

Myinvention relates to outlet boxes.-

An object of my invention is to provide a box of the above type which is self adjust- 1n It is well known in this art-that the outlet boxes which are now commo-nly used-have proven unsatisfactory. lOne great diiiiculty is that after the box has been embedded in concrete or the like and the concrete hardens, and shifts slightly, the box fails togive with the concrete and is often broken. Again if the box is merely secured to. the framework of a house and the house shifts or settles the box fails to give and very often it is broken.

One great object a workman has in view during the installation of ari outlet box is to keep the same water-proof that is all the joints thereof are to be so secured as to revent any leakage. When the boxes that have been heretofore devised shifta little, many of' these joints Iare broken if the box isnot broken itself.

Itis -my object to overcome the above mentioned ditliculty and to provide an outlet box which is self adjusting and one wherein a water-tight joint is maintained at all times.

Another object of my invention is to provide an outlet box which is simple in construct-ion and one which can be manufactured at a very low cost.

With the foregoing and other objects in view, my inventlon consists in such details ofconstruction and in the arrangement and combination of parts as will be hereinafter fully described and lspecifically pointed out in t-he appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in whichi* Figure 1 is a vertical sectional view of my improved outlet box. Fig. 2 is .a vertical sectional View of my box showing the saine slightly shifted. Fig. 3 is a side elevation -opening is adapted to of a detail. Fig. 4 is a top plan View of a detail. Fig. `5 is a vertical' sectional view of what is known as a bell-nozzle., Fig.f6 is a vertical sectional viewof Vwhat is known as a drip-nozzle.

In the draw-ings the line 2-2 indicates the surface of a door and the line 3 3 indicates the upper surface of the ceiling.

I preferably dispose my outletbox between the floor and the ceiling of the room below, but I do` not limitmyself to this speclc disposition, and desire it to be understood that the same may be used and disposed in many other different positions.

1 designates the body port-ion ofmy outlet box the same being provided with the annular ange 2 at the lower sides thereof. I further provide the box 1 with the internally screw threaded sleeves 3 which are are adapted to receive electrical conduits (not shown). `The box4 l is further provided at its upper end with the opening 4, which receive the downwardly projecting collar 5 of the annular disk 6. For a purpose that will be hereinafter fully described, the disk 6 is provided with the struck down portion 7. The struck down portion 7 is provided with the opening 8, which opening is adapted to reg` lster with an openingrl 9 which is formed within a plate l0 which plate is secured to the surface ofa licor as by means of screws or otherwise (not shown). I 'dispose between the plate 10 and the disk 6, a gasket l1, for an obvious purpose.

It will be readily seen from the foregoing that the box'l is allowed to move upon t-he collar 5 in such.a manner as to always maintaln a perfect connection therewith. It will also be readily seen that a box can not only be adjusted from side to side but can be also adjusted vertically.

In Figs. 5 and 6 I have illustrated different forms of nozzles which arecommonly known connected with outlet boxes. Either form of these nozzles may be used, I not limiting myself to either.

I desire to la-y great stress upon the simplicity of my device and it is thought that the advantages and novel features of the 105 device will be readily appreciated from the foregoing disclosure.

I desire it to be understood that I may make slight changes in the construction and in the arrangement and combination of parts 110 without departing from the spirit of my invention, providedlsuch changes fall within the scope of the appended claims. v

Having thus fullyl described my'invention, what I claim as new anddesire to secure by Letters Patent is 1. An outlet box device of the class deJ scribed comprising first and second members throughy which circuit wires pass, a separate fastening means for each of said members, one of said rmembers having a part loosely and freely extending into the other member when fastened, whereby the parts can move relatively.

2. An outlet box device of the class described comprising first and second members through which circuitwirespass, one of said members having a part loosely and freely extending into the other member so that said members can move relatively when desired, and a separate fastening means for each of said members whereby each of said members is attachable to separate parts.

3. An youtlet box device of the class-de scribed comprising first and second members through which circuit wires pass, means to attach the irst member to a support and said first member havin a, projecting member extending loosely an freely into the second member, whereby the said members may be moved relatively when fastened, the second member having a ange by means of which attachment may be made to a support separate from the support for the first member.

4. An outlet box device of the class described comprising first and second members through which circuit wires pass, said first member comprising a hollow box open at one end and having an inlet openin for circuit wires, said box also having a ange by means ofwhich it may be attached to a support, said second member comprising. a disk to loosely rest on the box, a collar extending from said disk and into the box loosely and freely at its open end, said disk and collar connection permitting the members to move relatively when fastened, said disk between the wall of said collar provided with an opening for circuit wires, and means to attach said disk to a su `port se arate Afrom the support to whcii the rst member is attached.
